Recycled Tapialblock: Eco-innovative Materials for a Circular Economy

Fetdeterra | Macari de Torres Mestres | Maite Sainz de la Maza Benet

Recycled tapialblock: prefabricated block with earth and recycled aggregates without baking. 


Recycled Tapialblock is a prefabricated block with earth and recycled aggregates without baking, where the principles of Circular Economy are applied in the construction sector.

It is an Eco-innovative project. We use 100% recycled material. In the manufacturing process, existing precast concrete technology is reused. The product obtained is unique and capable of meeting the actual needs on the market.

The development of the project is based on solving environmental problems that affect the construction and rehabilitation of buildings, with the aim of Reducing, Recycling and Reusing.

The objective of the Fetdeterra stand project at Construmat, was the presentation of Tapialblock. The stand was designed with the premise of coherence among the stand and the new product. Our efforts were focused on enhancing the presence of the material, and turning the visit to the stand into an experience to enjoy the sensations transmitted by the material itself.
Design Bases of:
-Use of a single material, the Tapialblock.
-Quick assembly and dismantling, thanks to the prefabricated system.
-The blocks are dry placed, to be able to reuse 100% of the blocks, and not generate any waste.
-Minimize costs in material, assembly and disassembly.

With this project, we obtain a positive social impact of the acceptance of the product, which is confirmed with the 1st prize obtained as innovative material at the fair. Minimal impact on the environment, achieved through the non-generation of waste, before, during or at the end of the event. Low economic impact by eliminating the cost of the material, by reusing 100% of the product, the blocks are recovered and then placed in a single-family house.
